David Chalmers (philosopher)

David Chalmers is an Australian philosopher best known for his work on consciousness. He explores why and how subjective experience—the feeling of "what it’s like" to see, hear, or feel—exists. Chalmers distinguishes between the physical processes in the brain and the personal, first-hand experience, calling this the "hard problem of consciousness." He argues that understanding consciousness involves more than just studying brain activity, posing deep questions about how physical information gives rise to subjective experience. His work influences ongoing debates about mind, brain, and the nature of reality.
